Older adults show extensive variability in cognitive performance, including episodic memory. A portion of this variability could potentially be explained by genetic factors. Recent literature shows that the neurotransmitter serotonin plays an important role in memory processes, as enhancements of brain serotonin have led to memory improvement. Here, we have begun to explore genetic contribution...

With the development of the Internet and organizational intranets, it has become an increasingly critical and difficult task to monitor large and complex networks indispensable to security risk management and network performance analysis. Monitoring for security situational awareness with visualization has been shown to be an effective and efficient approach. However, the quality of source data...

Archives of distributed workloads acquired at the infrastructure level reputably lack information about users and application-level middleware. Science gateways provide consistent access points to the infrastructure, and therefore are an interesting information source to cope with this issue. In this paper, we describe a workload archive acquired at the science-gateway level, and we show its ad...

Massive Open Online Courses (MOOCs) have emerged as a significant environment for online learning, yet little is known about how people actually learn in a MOOC. The study brings together qualitative data from parallel studies in two different MOOCs, comparing learning strategies of people who self-report low and high levels of Self-Regulated Learning (SRL). This comparative study identifies co...

Management of hypertension (HTN) largely relies on proper and accurate measurement of blood pressure (BP). Even following the criteria for HTN diagnosis defined in the Fourth report on high BP in children and adolescents, inaccurate diagnosis and misdiagnosis can occur with white coat effect and masked HTN. The use of Ambulatory Blood Pressure Monitoring (ABPM) has been increasing in pediatrics...

To act autonomously and robustly in complex environments, mobile robots require task planning to adapt to the given situation. With the growing capabilities of robot hardware and software this is becoming increasingly important. Yet, only few integrated robotic systems exist. This thesis attempts to make a next step towards robust plan-based robot control. For this, it first describes how the H...
